qBittorrent 4.6.6 was working flawlessly… until yesterday. I updated qBittorrent from 4.6.6 to 4.6.7 and it doesn’t work anymore. I had to roll it back… and now it works again.
Again, you need to be more specific re. “doesn’t work”, but check to see if version 4.6.7 is whitelisted on the tracker(s) you’re trying to connect to. Their admins may not have added it yet.
It should go without saying, but I’m gonna say it anyway: don’t update to chart version 1.2.15, as it introduces qBittorrent 5.0.0, which no one has whitelisted yet
